Application led Decembwer 2, 1910, Serial No. 595,324. Renewed January 24, 1914. Serial No. 814,236.

To all vwhom it may concern.'

Be it known that I, CHARLE F. P. ANDERS, a subject of the Emperor of Germany, and resident of' Hoboken, inthe county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Vacuum-Bottles, of which the following is a specification.

rl`his invention relates to what are known as vacuum bottles and in the particular form shown, it has reference to such bottles having therein two receptacles so that it may hold two separate things. It is of course the purpose of such bottles to maintain the contents at the same temperature whether hot or cold and to'prevent the passage of heat from the bottle to the outside atmosphere or -the heat from the atmosphere to the contents of the bo-ttle.

It has been my object to produce bottle which can be easily and cheaply made and in which the parts will be firmly supported and at the sarre time the contents will be more effectively protected against changes of temperature.

The novel features of the invention will be apparent from the following description taken in connection with the accompanying drawings.

In the drawings, Figure` 1 is a longitudinal section through a device embodying the main features of my invention; Figs. 2, 3 and 4 are sectional views of the portion of a bottle showing modified forms of supporting and insulating means; and Fig. 5 is a detail perspective view of one form of supv porting frame which may be used in my de` vice.

As will be seen by reference to Fig. 1, the outer Vall 1 is preferably made cylindrical in form having the reduced or contracted upper end or neck 2, and it will of course be understood that this wall is made of glass. An inner receptacle` 3 somewhat smaller in diameter than the wall is inserted through the lower end 4 and its reduced or contracted neck 5 is fused to the outer edge ofv the neck 2, so that the inner receptacle and outer wall are integrally connected at the lip or mouth and are separated at all other points by a vacuum space. The lower end 6 of the inner receptacle is tapered as shown for the purpose hereafter described. A seco-nd inner receptacle 7 of slightly smaller diameter than the outer wall is inserted through the open end 4 and it hasV the enlarged neck 8 which is fused at its edge to the lower edge of the outer wall So as to make the inner receptacle in one piece with the outerwall. This second inner receptacle has a tapered lower end 9 and before it is placed in position as above described, I place within the outer wall and over the end (i of the inner receptacle 3 a centering, spacing and heat insulating device such as shown in the drawings, the tapered end 9 of the receptacle 7 fitting into one side of this device and the tapered end 6 fitting into the other side. This device serves to support and center the two inner receptacles and this strengthens the device as a whole and prevents breakage, but it is so constructed and arranged that it will practically conduct no heat fro-m the inner receptacle to the outer wall or from one inner receptacle to the other. The neck 5 of the upper' inner receptacle is closed by a stopper 10 having the upper wall 11 and the lower wall 12 leaving a vacuum space between for the purpose of insulation. The lower neck 8 has therein a closure 13 having the outer wall 14 and the inner wall 15, leaving a vacuum space whereby the contents of the inner receptacle is protected from changes in temperature outside of the receptacle. At the point 16 there is an opening in the outer wall during the operations above described in the manufacture of the device, but after the inner receptacles and outer wall are in place and fused together in one integral who-le the air surrounding the inner receptacles is eX- hausted through this opening and it is then sealed as shown so as to maintain the vacuum.

The spacing and centering device as shown in Fig. 1 consists of two duplicate frames 17, 18, having the spider legs 19, 20. The spider legs or resilient arms extend from the central ring like portions at an angle downwardly and outwardly to the outer wall 1, the ends 0f the legs being curved upwardly as shown so as to give a flexible connection or yielding contact with the outer wall. The bends in the legs 19 and 20 providing feet which rest upon opposite sides of a mica disk 21 which fits within the outer wall and which by reason of the fact that it is a poor conductor of heat will serve as an insulation. The central ring like portions of the two frames 17 and 18 have at their inner edge the short lugs 22, 23 at intervals, and at their outer edge they have longer integral upwardly projecting bent parts or lugs 24, 25. Flat ring like disks 26, 27 of mica rest on the lugs 22, 23 and bear at their outer edge against the lugs 24, 25 and as shown the central opening in these mica plates is smaller than the openings in the metal frames. The tapered ends 6 and 9 of the inner receptacles bear on the inner edges of these mica rings and thus the mica rings serve as an insulation preventing the passage of heat between the inner receptacles and the outer wall. The flexible or resilient nature of the parts, furthermore, serves to furnish a yielding support and centering device for both the invner receptacles, holding them securely in position and preventing breakage due to jars. It will be understood that these parts of the device are inserted after the inner receptacle 3 has been secured in place and before the inner receptacle 7 is inserted.

In Fig. 2, I have shown a coil spring 28 which is inserted between the inner pointed ends of the inner receptacles and it serves to support and center those receptacles and lform of means for supporting and centering the two inner receptacles and 1n th1s in- A stance, I make use of an upper frame 29` at the same time furnishes little opportunity for the passage .of heat from one to the other. .This form of yielding connection between the parts may be used in place of that described in connection with Fig. 1, but I prefer that shown in Fig. 1.

In Fig. 3, I have shown another modied having radial arms or legs 30 extending at an angle out to the outer wall 1 and on this frame I support the mica disk 31 in the way described in connection with Fig. 1 surrounding the end 6 of the inner receptacle. A second frame 32 carries a mica disk 33 surrounding the end 9 of the inner receptacle and having the curved radial legs 34, which legs have at their outer ends notches so as to make them embrace the legs 30 of the other frame as is shown clearly in Fig. 5. The two frames in this form are therefore flexibly or yieldingly supported from each other and are also supported from the outer wall so'as to properly center and support the inner receptacle or receptacles.

In Fig. 4, I have shown a modified construction similar to that shown in Fig. 3 with the exception that I have placed a Hat circular disk of fibrous material 35 over the mica disk 31, and the inner receptacle rests against this disk made of iber. A similar disk 36 is placed on the lower frame on the mica disk 33and this forms a still more lei'ective means forinsulating the inner receptacles to prevent the passage of heat be- `tween those receptacles'l and the outer atmosphere.

It will be understood that one or more disks may be used in each of the forms disclosed for supporting the inner receptacles and that various modications in the structure may be made without departingfrom my invention.

It is to be understood that in this application a wide-mouth inner or outer member means an inner or outer member which has a mouth substantially as great in diameter as the body of the member, and that a narrow-mouth inner or outer member means an inner or outer member' which has a mouth considerablysmaller in diameter than the body of said member.
